Public bug reported:

A recently merge patch separates the lock required to delete an instance
from the one used during instance creation and other operations.

This leads to race conditions in the Hyper-V driver, as the spawn and
destroy methods have been written considering that locking already
occurs at the compute manager level.

This patch has already been committed, reverted  and committed again:
